FreeCAD Legacy Migration

From Open Source Ecology
Jump to: navigation, search


This page is meant to document the motivation of why OSE should migrate away from FreeCAD 16 or FreeCAD Legacy.


The following are the compelling new features we're missing out on that could vastly transform how we use FreeCAD.

Costs of Not Using the Latest FreeCAD Version

  • You'll copy and paste snippets from Googling help online and they won't work for you because they're only available in a later version of FreeCAD
  • Less help on the FreeCAD forums
    • According to the FreeCAD Forum Rules, you must "Make sure your FreeCAD version is up to date" before posting.
    • I was told on my first post for help on the forums that my versions were "obsolete" and I should be using the latest. See the following post and reply.
  • Additional overhead of writing Python 2 and Python 3 compatible code
  • Additional overhead of writing FreeCAD 16, 17, 18, and 19 compatible code
  • Not motivated to contribute meaningful code contributions to FreeCAD
    • Why contribute new features or bug-fixes if we aren't able to get those new features or bug-fixes since those will only be included in the latest released version of FreeCAD instead of being back-ported to FreeCAD Legacy
  • External workbenches like the Fasteners Workbench have moved on from FreeCAD Legacy, Python 2, and QtGui 4, and so we won't get any new features or bug-fixes unless we use the latest version of FreeCAD
  • Less engagement with FreeCAD community as our tutorials, resources, and software our geared towards Legacy FreeCAD which the community has moved on from

Python 2 Is No Longer Supported!!!

Python 2 was sun-setted on January 1, 2020. That means the Python Software Foundation will not improve it anymore after that day, even if someone finds a security problem in it. You should upgrade to Python 3 as soon as you can.
